Abstract

Background: Sedentary behavior has potential risk factors adverse impacts on health outcomes and have been trend to be increased. This lifestyle directly effects on respiratory and cardiovascular systems. Inspiratory muscle training is a simple and safe method that has been shown to significantly improve respiratory and circulatory function. Therefore, the method is beneficial for reducing the risk of sedentary behaviors.


Objective: To compare the effects of inspiratory muscle training on respiratory muscle function and exercise capacity among individuals with sedentary behavior.


Methods: This study was a single-blinded, randomized controlled trial. Thirty-two sedentary participants were divided into inspiratory muscle training and control groups, with sixteen participants in each group. Measurements of inspiratory and expiratory muscle strengths and endurance, 6-minute walking distance, and peak oxygen consumption were taken pre- and post-training. Unpaired-t test and paired-t test statistics were used. The significant difference was set at 0.05.


Results: After 4 weeks of training, significant differences between the two groups were found in respiratory muscle strength, 6-minute walk distance, and peak oxygen consumption (p<0.001) and respiratory muscle endurance (p=0.028). Respiratory muscle strength, 6-minute walk distance, and peak oxygen consumption were significant differences between pre- and post-inspiratory muscle training (p<0.001).   


Conclusion: The 4-week respiratory muscle training effectively improved respiratory function and exercise capacity in individuals who are sedentary behavior.
